Paris — Climate change played a key role in last year’s record-low levels of Antarctic sea ice, a study published on Monday found, marking an abrupt shift from the growth seen in previous decades.

Scientists from the British Antarctic Survey (BAS) found that human-caused global warming resulted in a once-in-2,000-year low in ocean surface around the continent blanketed by ice.

Compared to an average winter over the last several decades, the maximum extent of Antarctic sea covered by ice shrank by two million square kilometers — an area four times the size of France, the BAS said.

“This is why we were so interested in studying what climate models can tell us about how often large, rapid losses like this are likely to happen,” the study’s lead author Rachel Diamond told AFP.

Scientists, having analyzed 18 distinct climate models, found that climate change quadrupled the likelihood of such large and rapid melting events.

Understanding the cause of sea ice melt is complex as there are many variables — from ocean water to air temperature to winds — that can effect it, scientists say.

But determining the role of climate change is critical since ice formation has global impacts from ocean currents to sea-level rise.

Sea ice, which forms from freezing salt water already in the ocean, has no discernible impact on sea levels.

But when highly reflective snow and ice give way to dark blue ocean, the same amount of the Sun’s energy that was bounced back into space is absorbed by water instead, accelerating the pace of global warming.

Recovery unlikely

Unlike the Arctic, where sea ice has been declining since satellite records began in the 1970s, the melt trend in Antarctica is a more recent phenomenon.

Antarctic sea ice increased “slightly and steadily” from 1978 until 2015, according to the BAS.

But 2017 brought a sharp decline, followed by several years of low ice levels.

In the study published in the journal Geophysical Research Letters, BAS researchers also ran projections to see whether the ice would return.

“It doesn’t completely recover to original levels even after 20 years,” Diamond told AFP. That means “the average Antarctic sea ice may still stay relatively low for decades to come”, he added.

“The impacts… would be profound, including on local and global weather and on unique Southern Ocean ecosystems — including whales and penguins,” co-author Louise Sime said.

Previous studies by the BAS have shown that the abnormal melt has led to the deaths of thousands of emperor penguin chicks.

Reared on the ice sheets, they perished when they were plunged into the ocean before they had developed their waterproof feathers.

London — The final report of the U.K.’s infected blood inquiry will be published Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from transfusions of tainted blood and blood products in the 1970s and 1980s.

The scandal is widely seen as the deadliest to afflict Britain’s state-run National Health Service since its inception in 1948, with around 3,000 people believed to have died as a result of being infected with HIV and hepatitis, an inflammation of the liver.

The report is expected to criticize pharmaceutical firms and medical practitioners, civil servants and politicians, although many have already died given the passage of time. It’s also set to pave the way to a huge compensation bill that the British government will be under pressure to rapidly pay out.

Had it not been for the tireless campaigners, many of whom saw loved ones die decades too soon, the scale of the scandal may have remained hidden forever.

“This whole scandal has blanketed my entire life,” said Jason Evans, who was four when his father died at the age of 31 in 1993 after contracting HIV and hepatitis from an infected blood plasma product.

“My dad knew he was dying and he took many home videos, which I’ve got and replayed over and over again growing up because that’s really all I had,” he added.

Evans was instrumental in the decision by then-Prime Minister Theresa May to establish the inquiry in 2017. He said he just “couldn’t let it go.” His hope is that on Monday, he and countless others, can.

Here is a look at what the scandal was about and what the report’s impact may be.

What is the infected blood scandal?

In the 1970s and 1980s, thousands of people who needed blood transfusions, for example after childbirth or surgery, became exposed to blood tainted with hepatitis, including an as yet unknown kind that was later termed Hepatitis C, and HIV.

Those with haemophilia, a condition affecting the blood’s ability to clot, became exposed to what was sold as a revolutionary new treatment derived from blood plasma.

In the U.K., the NHS, which treats the majority of people, started using the new treatment in the early 1970s. It was called Factor VIII. It was more convenient when compared with an alternative treatment and was dubbed a wonder drug.

Demand soon outstripped domestic sources of supply, so health officials began importing Factor VIII from the U.S., where a high proportion of plasma donations came from prisoners and drug users who were paid to donate blood. That dramatically raised the risk of the plasma being contaminated.

Factor VIII was made by mixing plasma from thousands of donations. In this pooling, one infected donor would compromise the whole batch.

The inquiry heard estimates that more than 30,000 people were infected from compromised blood or blood products via transfusions or Factor VIII.

Missed chances

By the mid 1970s, there was evidence haemophiliacs being treated with Factor VIII were more prone to hepatitis. The World Health Organization, which had warned in 1953 of the hepatitis risks associated with the mass pooling of plasma products, urged countries not to import plasma.

AIDS, the biggest public health crisis since World War II, turned up in the early 1980s. Originally thought to be isolated to the gay community, it soon started appearing among haemophiliacs and those who had received blood transfusions.

Though the cause of AIDS — HIV — was not identified until 1983, warnings had been relayed to the U.K. government the year before that the causative agent could be transmitted by blood products. The government argued there was no conclusive proof. Patients were not informed of the risk and persisted with a treatment that put them in mortal danger.

Mistakes

The inquiry is expected to conclude that lessons from as early as the 1940s had been ignored.

Campaigners argue that since the 1940s it had been clear that heat killed hepatitis in another plasma product, albumin. They say authorities could have made Factor VIII safe before it was sold.

Evidence given to the inquiry suggested that authorities’ main objection was financial. Non-heated Factor VIII was prescribed by the NHS until late 1985.

Campaigners hope the inquiry’s core finding is that Factor VIII concentrates should never have been licensed for use unless heated.

Why now?

In the late 1980s, victims and their families called for compensation on the grounds of medical negligence. Though the government set up a charity to make one-off support payments to those infected with HIV in the early 1990s, it did not admit liability or responsibility and victims were pressured to sign a waiver undertaking not to sue the Department of Health to get the money.

Crucially, the waiver also prevented victims from suing for hepatitis, even though at that stage they only knew about their HIV infection. Years after signing, victims were told they had also been infected with hepatitis, mainly Hepatitis C.

There was no further group litigation until Evans, whose mother “crumbled” after his father’s death and who was called “AIDS boy” at school, brought a case claiming misfeasance in public office against the Department of Health.

Combined with political and media pressure, May announced the independent inquiry. It was, she said, “an appalling tragedy which should simply never have happened.”

Compensation

The government has accepted the case for compensation, with most estimates putting the final bill in the region of $12.7 billion. In October 2022, authorities made interim payments of 100,000 pounds to each survivor and bereaved partners.

The government is expected to announce different payments for different infections and address how and when bereaved families can apply for interim payments on behalf of the estates of people who have died.

Washington — After a nearly two year hiatus, Blue Origin flew adventurers to space on Sunday including a former Air Force pilot who was denied the chance to be the United States’ first Black astronaut decades ago. 

 

It was the first crewed launch for the enterprise owned and founded by Amazon billionaire Jeff Bezos since a rocket mishap in 2022 left rival Virgin Galactic as the sole operator in the fledgling suborbital tourism market. 

 

Six people including the sculptor Ed Dwight, who was on track to become NASA’s first ever astronaut of color in the 1960s before being controversially spurned, launched around 09:36 am local time (1436 GMT) from the Launch Site One base in west Texas, a live feed showed. 

 

Dwight — at 90 years, 8 months and 10 days — became the oldest person to ever go to space. 

 

“This is a life-changing experience, everybody needs to do this,” he exclaimed after the flight. 

 

Dwight added: “I thought I didn’t really need this in my life,” reflecting on his omission from the astronaut corps, which was his first experience with failure as a young man. “But I lied,” he said with a hearty laugh. 

 

Mission NS-25 is the seventh human flight for Blue Origin, which sees short jaunts on the New Shepard suborbital vehicle as a stepping stone to greater ambitions, including the development of a full-fledged heavy rocket and lunar lander. 

 

To date, the company has flown 31 people aboard New Shepard — a small, fully reusable rocket system named after Alan Shepard, the first American in space. 

The program encountered a setback when a New Shepard rocket caught fire shortly after launch on September 12, 2022, even though the uncrewed capsule ejected safely. 

 

A federal investigation revealed an overheating engine nozzle was at fault. Blue Origin took corrective steps and carried out a successful uncrewed launch in December 2023, paving the way for Sunday’s mission. 

 

After liftoff, the sleek and roomy capsule separated from the booster, which produces zero carbon emissions. The rocket performed a precision vertical landing. 

 

As the spaceship soared beyond the Karman Line, the internationally recognized boundary of space 100 kilometers above sea level, passengers had the chance to marvel at the Earth’s curvature and unbuckle their seatbelts to float — or somersault — during a few minutes of weightlessness. 

 

The capsule then reentered the atmosphere, deploying its parachutes for a desert landing in a puff of sand. However, one of the three parachutes failed to fully inflate, possibly resulting in a harder landing than expected. 

 

Bezos himself was on the program’s first ever crewed flight in 2021. A few months later, Star Trek’s William Shatner blurred the lines between science fiction and reality when he became the world’s oldest ever astronaut aged 90, decades after he first played a space traveler. 

 

Dwight, who was almost two months older than Shatner at the time of his flight, became only the second nonagenarian to venture beyond Earth. 

 

Astronaut John Glenn remains the oldest to orbit the planet, a feat he achieved in 1998 at the age 77 aboard the Space Shuttle Discovery. 

 

Blue Origin’s competitor in suborbital space is Virgin Galactic, which deploys a supersonic spaceplane that is dropped from beneath the wings of a massive carrier plane at high altitude. 

 

Virgin Galactic experienced its own two-year safety pause because of an anomaly linked with the 2021 flight that carried its founder British tycoon Richard Branson into space. But the company later hit its stride with half a dozen successful flights in quick succession. 

 

Sunday’s mission finally gave Dwight the chance he was denied decades ago. 

 

He was an elite test pilot when he was appointed by President John F Kennedy to join a highly competitive Air Force program known as a pathway for the astronaut corps, but was ultimately not picked. 

 

He left the military in 1966, citing the strain of racial politics, before dedicating his life to telling Black history through sculpture. His art, displayed around the country, includes iconic figures like Martin Luther King Jr, Frederick Douglass, Harriet Tubman and more.

mbale, uganda — Barbara Nabulo was one of three girls in her family. But when a sister died, her mother wailed at the funeral that she was left with just one and a half daughters.

The half was the ailing Nabulo, who at age 12 understood her mother’s meaning.

“I hated myself so much,” Nabulo said recently, recalling the words that preceded a period of sickness that left her hospitalized and feeding through a tube.

The scene underscores the lifelong challenges for some people with sickle cell disease in rural Uganda, where it remains poorly understood. Despite Nabulo’s knowledge of how the disease weakens the body, she spoke repeatedly of “the germ I was born with.”

Infections, pain, organ damage

Sickle cell disease is a group of inherited disorders in which red blood cells — normally round — become hard, sticky and crescent shaped. The misshapen cells clog the flow of blood, which can lead to infections, excruciating pain, organ damage and other complications.

The disease, which can stunt physical growth, is more common in malaria-prone regions, notably Africa and India, because carrying the sickle cell trait helps protect against severe malaria. Global estimates of how many people have the disease vary, but some researchers put the number between 6 million and 8 million, with more than 5 million living in sub-Saharan Africa.

The only cure for the pain sickle cell disease can cause is a bone marrow transplant or gene therapies such as the one commercially approved by the U.S. Food and Drug Administration in December. Last week, a 12-year-old boy last week became the first person to begin the therapy.

Those options are beyond the reach of most patients in this East African nation, where sickle cell disease is not a public health priority despite the burden it places on communities. There isn’t a national database of sickle cell patients. Funding for treatment often comes from donor organizations.

A patient, a caregiver

In a hilly part of eastern Uganda that’s a sickle cell hot spot, the main referral hospital looks after hundreds of patients arriving from nearby villages to collect medication. Many receive doses of hydroxyurea, a drug that can reduce periods of severe pain and other complications, and researchers there are studying its effectiveness in Ugandan children.

Nabulo, now 37, is one of the hospital’s patients. But she approaches others like her as a caregiver, too.

After dropping out in primary school, she has emerged in recent years as a counselor to fellow patients, speaking to them about her survival. Encouraged by hospital authorities, she makes weekly visits to the ward that has many children watched over by exhausted-looking parents.

Nabulo tells them she was diagnosed with sickle cell disease at 2 weeks old, but now she is the mother of three children, including twins.

Such a message gives hope to those who feel discouraged or worry that sickle cell disease is a death sentence, said Dr. Julian Abeso, head of pediatrics at Mbale Regional Referral Hospital.

Some men have been known to divorce their wives — or neglect them in search of new partners — when they learn that their children have sickle cell disease. Frequent community deaths from disease complications reinforce perceptions of it as a scourge.

Health workers encourage testing

Nabulo and health workers urge openness and the testing of children for sickle cell as early as possible.

Abeso and Nabulo grew close after Nabulo lost her first baby hours after childbirth in 2015. She cried in the doctor’s office as she spoke of her wish “to have a relative I can call mine, a descendant who can help me,” Abeso recalled.

“At that time, people here were so negative about patients with sickle cell disease having children because the complications would be so many,” the doctor said.

Nabulo’s second attempt to have a child was difficult, with some time in intensive care. But her baby is now a 7-year-old boy who sometimes accompanies her to the hospital. The twin girls came last year.

Speaking outside the one-room home she shares with her husband and children, Nabulo said many people appreciate her work despite the countless indignities she faces, including unwanted stares from people in the streets who point to the woman with “a big head” — a manifestation of the disease in her. Her brothers often behave as if they are ashamed of her, she said.

Once, she heard of a girl in her neighborhood whose grandmother was making frequent trips to the clinic over an undiagnosed illness in the child. The grandmother was hesitant to have the girl tested for sickle cell when Nabulo first asked her. But tests later revealed the disease, and now the girl receives treatment.

“I go to Nabulo for help because I can’t manage the illness affecting my grandchild,” Kelemesiya Musuya said. “She can feel pain, and she starts crying, saying, ‘It is here and it is rising and it is paining here and here.'”

Musuya sometimes seeks reassurance. “She would be asking me, ‘Even you, when you are sick, does it hurt in the legs, in the chest, in the head?’ I tell her that, yes, it’s painful like that,” Nabulo said.

Nabulo said she was glad that the girl, who is 11, still goes to school.

The lack of formal education is hurtful for Nabulo, who struggles to write her name, and a source of shame for her parents, who repeatedly apologize for letting her drop out while her siblings studied. One brother is now a medical worker who operates a clinic in a town not far away from Nabulo’s home.

“I am very happy to see her,” said her mother, Agatha Nambuya.

She recalled Nabulo’s swelling head and limbs as a baby, and how “these children used to die so soon.”

But now she knows of others with sickle cell disease who grew to become doctors or whatever they wanted to be. She expressed pride in Nabulo’s work as a counselor and said her grandchildren make her feel happy.

“At that time,” she said, recalling Nabulo as a child, “we didn’t know.”

BEIJING — Cases of bird flu have been confirmed among wild fowl in western China, the agriculture ministry said Saturday, as concerns grow over a U.S. outbreak infecting cattle. 

Two counties in Qinghai province confirmed 275 cases of H5 influenza among dead Pallas’s gull and other wild birds, China’s Ministry of Agriculture and Rural Affairs said in a notice on its website. 

The ministry received a report on the cases from the China Animal Disease Control Center, and the national Avian Influenza Reference Laboratory confirmed the finding, the notice said. 

The H5N1 outbreak among dairy cattle in at least nine U.S. states since late March has raised questions over whether it could spread to humans. No such cases have been reported. 

The U.S. announced on May 11 that it would spend close to $200 million to fight the outbreak. 

News of the China bird flu cases came as the nation’s anti-graft watchdog announced a corruption probe of the agriculture minister Saturday. 

Tang Renjian, 61, is under investigation for “serious violations of discipline and law” by the Central Commission for Discipline Inspection and National Supervisory Commission, CCDI said on its website. 

The term is CCDI’s typical euphemism for corruption. 

The notice gave no further details.

NEW DELHI — Parts of northwest India sweltered under scorching temperatures Saturday, with the capital, New Delhi, under a severe weather alert as extreme temperatures struck parts of the country.

India’s weather department expects heat wave conditions to persist across the north for the next few days and has put several states on high alert.

On Friday, parts of New Delhi reported up to 47.1 degrees Celsius (116 Fahrenheit). The nearby states of Punjab, Haryana and Rajasthan also saw temperatures soar; they are likely to stay high over the next few days, said Soma Sen Roy, a scientist at the India Meteorological Department.

Roy cautioned people against going outdoors under the afternoon sun. He advised drinking plenty of water and wearing loose-fitting clothes. Those who are especially vulnerable, such as the elderly, should stay indoors, he said.

The extreme temperatures coincide with a six-week-long general election, with experts worried that the heat wave could increase health risks as people wait in long lines to cast their vote or candidates campaign aggressively in the outdoors. One minister fainted due to heat last month while addressing an election rally in Maharashtra state.

Prime Minister Narendra Modi and his main challenger, Rahul Gandhi of the opposition Congress Party, were expected to hold rallies in New Delhi later Saturday, as the city heads to the polls on May 25.

Satish Kumar, a 57-year-old rickshaw driver in the capital, said his work was suffering because of the heat. “People are not coming outside, [markets] are nearly empty,” he said.

Pravin Kamath, a 28-year-old who runs a cart selling cold drinks, complained that it was so hot he could hardly stand being outdoors. “But I must work. What can I do? I am poor, so I have to do it.”

The main summer months — April, May and June — are always hot in most parts of India before monsoon rains bring cooler temperatures. But the heat has become more intense in the past decade and is usually accompanied by severe water shortages, with tens of millions of India’s 1.4 billion people lacking running water.

A study by World Weather Attribution, an academic group that examines the source of extreme heat, found that a searing heat wave in April that struck parts of Asia was made at least 45 times more likely in some parts of the continent by climate change.

Climate experts say extreme heat in South Asia during the pre-monsoon season is becoming more frequent and the study found that extreme temperatures are now about 0.85 C (1.5 F) hotter in the region because of climate change.

At least 28 heat-related deaths were reported in Bangladesh, as well as five in India, in April. Surges in heat deaths have also been reported in Thailand and the Philippines this year, according to the study.

Extreme heat is fast becoming a public health crisis in India, with more than 150 people dying last year during heat waves. The government estimates nearly 11,000 people have died during heat waves this century, yet experts say such figures are likely a vast undercount.
